PROBLEM TO BE SOLVED: To provide a method of electrodeposition directly on a semiconductor.SOLUTION: There is provided the method of electrodeposition of a metal or metal alloy on at least one surface of a semiconductor material. The method provides full coverage of an electrodeposited metallic film on the at least one surface of the semiconductor material. The method includes providing a semiconductor material. A metallic film is applied to at least one surface of the semiconductor material by an electrodeposition process. The electrodeposition process employed uses current waveforms that apply a low current density initially, and after a predetermined period of time, the current density is changed to a high current density.
Abstract:
The invention is directed to a method of forming carbon nanomaterials or semiconductor nanomaterials. The method comprises providing a substrate and attaching a molecular precursor to the substrate. The molecular precursor includes a surface binding group for attachment to the substrate and a binding group for attachment of metal-containing species. The metal-containing species is selected from a metal cation, metal compound, or metal or metal-oxide nanoparticle to form a metallized molecular precursor. The metallized molecular precursor is then subjected to a heat treatment to provide a catalytic site from which the carbon nanomaterials or semiconductor nanomaterials form. The heating of the metallized molecular precursor is conducted under conditions suitable for chemical vapor deposition of the carbon nanomaterials or semiconductor nanomaterials.

PROBLEM TO BE SOLVED: To provide a crosslinked composition originated from living things and a manufacturing method for the same, and the structure thereof, and a manufacturing method for a printed circuit board originated from the living things using this composition. SOLUTION: A material originated from living things such as lignin, cereal oil, a wood resin, tannin, polysaccharides, and a mixture of these, etc., is cross- linked preferably using heat, a cross-linking agent and an initiator. The material thus produced has a property suitable for producing a printed circuit board. A cloth produced from glass fibers or from living things is impregnated with a mixture of the material originated from living things, the cross-linking agent, and the initiator, and then processed by a conventional method of obtain the printed circuit board.

SOLUTION: A photoresist composition comprises film formation polymer resin with phenol group. The phenol resin is copolymer of hydroxystyrene and hydroxycyclohexyl ethene shown by a formula I (n>1, 0
Abstract:
Chips mounted into substrates are often encapsulated with a cured epoxy which is insoluble. The invention herein is the discovery that diepoxides with ketal linkages are soluble. This permits encapsulating chips, testing them for goodness and removing the chips for rework by dissolving the epoxy without destroying the chip or substrate.
Abstract:
Biobased cross-linked compositions, methods of fabrication and structures, in particular biobased printed wiring boards using the compositions and methods of making the structures are described. Biobased materials such as lignin, crop oils, wood resins, tannins, and polysaccharides and combinations thereof are cross-linked, preferably using heat, a cross-linking agent, and an initiator. The materials fabricated have suitable properties for printed wiring boards which are made by impregnating a fibreglass or biobased cloth with an admixture of the biobased material, cross-linking agent and initiator which is processed by conventional methods to produce a printed wiring board.
